 So let's do our first scientific notation problem of the day. So we look at this, and this is a comma, not a decimal point. So how many significant digits does this number have? Just one. Okay, so you guys got to watch out about that. Those trailing zeros really kind of screw people up a lot. Okay? But when we're putting this into scientific notation, we have to take note of those placeholder zeros, those placeholder trailing zeros, and use the decimal and move over technique and everything that we showed before. Okay? So we're going to put our pretend decimal there, right? And then move it to where? After the first significant digit, right? To the left, definitely. But after the first significant digit, okay? So after that one, essentially, right? So one, two, three, four, five. Like that. Okay? So this had one significant digit, so our number down here is going to have how many significant digits? Just one. Okay? So don't change it, you know, don't change anything with the significant figure rules, okay? This number has to be exactly the same as the number that you started. Okay? So just the one is going to be significant, so it's going to be one times ten to the one. Okay? Okay? Like that. So I know sometimes you want to put more than just the one significant figure, but I don't know, resist that temptation, okay? So are there any questions about this one? You guys go down these ones.
